RGTARY tpecification of Letters Patent. Patented Sept. 3Q), 19199.

Application filed June to, 191%. Serial 1t'o. 239,1%.

To all toiwm it may concern:

Be it known that T, Leo Jonuv Barns, a

I citizen of the United "States, residing at St.

Louis, State of Missouri, have invented certain new and useful Improvements in R0- tary Valves, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, forming;

a part hereof.

The present invention is directed to improvements in rotary-valves, the particular lie An example of a specific application of the improved valve is that of a distributing valve for steam in a soot-blowing system such "as shown in. an application for 1mprovements in soot boiler cleaners filed concurrently herewith, or in any other system where it imdesired to distribute in difi'erent till directions a liquid, fluid, gas, or steam, from a common source of supply. A. further object is to provide a valve which, when operating on steam, may automatically drain all water of condensation bei ore the steam is delivered to any particular point of consumption. A further object is to provide a valve which shall be simple in construction, and one possessing further and other advantages better apparent from the following detailed description in connection with the accompany ing drawing in which igure 1 represents an end view looking toward the operating end of the valve; Fig. 2 is a view at right angles to Fig. 1; Fig. 3 is a middle longitudinal section on the line 33 of Fig. 1; Fig. 4 is a cross-section on the line l& of Fig. 2; and Fig. 5 is a view similar to Fig. 1 on a smaller scale showing the application of the pointer on the operating handle.

Referring to the drawings, 1 represents a valve casing or shell from the peripheral walls of which radiate a series of hollow bosses 2 (in the present example three in number) the axes of the bosses intersecting the longitudinal axis of the bore of the valve casing. Opposite the middle boss the wall of the casing is provided with a port 0 serving as a drain port for the steam when the valve is to be used in a steam blower system as above pointed out. The intake end i of the bore of the casing is interiorly threaded for securin theretb the end or a suitable steam supp y pipe 3, the opposite end being exteriorly threaded for receiving a flanged nut d by, which the gland 5 is firmly held against the packing ring 6 interposed betweenthe gland and the shoulder a of a chambered or hollow rotary valve or key V rotatable in the bore of the casing, the axis of the bore and valve being coincident. As seen in the drawing, the bore of the casing l tapers toward the intake end, the outer wall 1 of the valve being correspondingly tapered so as to form a tight joint with the walls or the bore. The chamber G of the valve is closed at the end opposite the intakeend i of the valvdcasing, said closed end being provided with a reduced polygonal or s uare extension 7 for engaging the socket of a wrench or operatinglever 8 as shown. The open end of-the valve terminates opposite the counter-bore or groove 9 formed in thewall of the bore of the casing adjacent the inner terminal of the threads in the intake 2'. The wall of the chambered portion of the valveV is provided with a port 7t elongated in the general direction of the longitudinal axis of the casing bore, said port being adapted to be brought into register with a corresponding elongated port it formed. in the peripheral wall of the casing at the base of each boss 2, the circular bore ofeach boss being screw-threaded for coupling to a suittable distributer pipe or header 10. When the valve or key is turned so to close all the ports 7b, the port it comes opposite the drain opening or port 0 (dotted position 1 Fig 4) so that any condensed steam may dram through said port and the drain pipe nozzles for conducting the fluid to predetermined points of consumption. It will be observed that the] fluid enters the valve chamber G along the common axis of the valve and bore of the casing, and is discharged from the valve through the casing steam or other fluid'is beingdelivered,YI 7 provide the handle 8 with a pointer p and at 'without 1n any scope of one of the corners of each of the polygonal terminals-of the bosses 2 I file away sufiicient metal to leave a fiat facet on which I mark respectively the numerals 1, 2, 3, designated by n (Fig. 5). Where the pointer p for example points to the numeral 3 it means that the port k of the valve is in register with the port it of the boss bearing said numeral. the numeral 2, it in register with the boss and that the fluid is being delivered to the pipe 10 leading from said boss. When the pointer points in a direction diametrically opposite to numeral 2 on the middle boss 2 (Fig. 5), it means that the port h of the valve is in register with the drain port 0, and that the fiuid has been cut oif from all of the bosses 2 and the distributing pipes 10 leadingtherefrom. The numerals 1, 2, 3, marked on the bosses 2, constitute means-that the port It is a dial for the pointer 19. It is of course ap-- hat I may resort to many. changes parent t I wise afl'ecting the nature or the invention. For example I need not limit myself to a valve with three ports h and three bosses 2, any other number falling under my invention. Neither need I restrict myself to a single opening to form a port. I may for example have a plurality of small openings with a combined area of a single large opening as must be clearly obvious to those skilled in the art.

The valve may be changed in other respects and yet come within the spirit of my invention.

Having described my invention what I- claim is: I

1. A valve comprisinga'casing rovided with a central tapering bore, one en of said When the pointer points toport h' of the middle bore as an intake, a chambered key mounted rotatably-in the bore of the casing andoperable from a point outside the eassol ing diametrically opposite the intake end of p f the bore, the chamber of the key being closed p at one end and open at the end: adjacent the intake, an exterior shoulder being formed on the key opposite the closed end of the cham-- ber thereof, a series of hollow bosses radiating from the casing and communicating with the bore through elongated ports formed in the wall of the casing, a reduced drain port in the casing wall opposite one of the elongated ports aforesaid, a packing ring bearing against the shoulder on the key, a

gland engaging the packing ring, and a nut Y on the casing controlling said gland and thereby holding the key against longitudinal displacement, the wall of the key chamber being provided with an elongated port adapted to be brought into-register with the portof any one of the bosses aforesaid.

2. A valve comprising a casing provided with a central tapering bore, one end of said bore serving as an intake, a chambered key mounted rotatably in the bore of the casing and operable from a point outside the casing diametrically opposite the intake end of the bore, the chamber of the key being closed at one end and open at the end adjacent the intake, the wall of the casing being provided with a series of discharge ports communicatingw-iththe bore, and bemg further provided with a reduced drain port commun1cat ing with the bore and spaced a suitable distance from the discharge ports on either side thereof, the wall of the key chamber being provided with a port corresponding substantially with the discharge ports of the casing and adapted to be brought into register with any of said ports or with the drain port.

In testimony whereof I aflix my signature,

in presence of two witnesses.
